Description
Technical field
The utility model relates to the lighting apparatus field.
Background technology
Energy shortage is the hot issue of the world today, and in illuminating industry, the LED light emitting diode is because multiple advantages such as its efficient, energy-saving and environmental protection, long-life are to replace the energy consumption height, the first-selection of the traditional lighting that the life-span is short.Existing led light source comprises LED and wiring board, and LED is by lamp wall, chip, epoxy resin and be configured to, and chip is located in the groove of cantilever tip, and chip is provided with fluorescent material, and lamp wall and cantilever tip are fixed by epoxy resin.The connected mode of led light source all is to adopt pins type, and promptly LED inserts in the wiring board by support and fixes, and on the wiring board a plurality of LED can be set.The defective of above-mentioned existing led light source is: the heat that chip produces when 1, working all dispels the heat by support, but because the area of support is little, heat radiation inconvenience, the heat that chip produces can not outwards discharge as soon as possible, make chip overheating damage, thereby influenced the service life of led light source; 2, the epoxy resin in the LED is subjected to ultraviolet interference easily, and after LED worked long hours, it is muddy that resin slowly can become, thereby influences the luminous efficiency of LED when work.
Summary of the invention
Goal of the invention of the present utility model is in order to overcome the deficiency that existing led light source exists, and provides that a kind of chip cooling speed is fast, long service life, led light source that luminous efficiency is good.
The technical solution of the utility model is: a kind of led light source, comprise LED and wiring board, and comprise that also aluminium base, aluminium base are provided with several bowl-type grooves, are provided with LED in the bowl-type groove; Described LED comprises chip and fluorescent material, and chip is fixed on the bowl-type groove bottom, and fluorescent material is located on the chip; Described wiring board is arranged on the aluminium base, and wiring board is connected by gold thread with chip.
As preferably, described wiring board is the copper foil circuit plate.
As preferably, described aluminium base is provided with installing hole.
As preferably, described aluminium base is provided with the bowl-type groove that several regular matrixs are arranged.
A kind of led light source by the technical solution of the utility model design does not re-use support, has increased aluminium base, chip is directly arranged in the bowl-type groove on the aluminium base, chip dispels the heat by aluminium base, and radiating rate is very fast, the bowl-type groove the irradiating angle that can strengthen LED is set.Do not re-use epoxy resin, working long hours also to influence the luminous efficiency of LED.The copper foil circuit plate not only conducts electricity, and can also distribute a part of heat by the gold thread that connects chip.Aluminium base is provided with installing hole, and the whole LED light source can be installed in the required light fixture easily.Aluminium base is provided with the bowl-type groove that several regular matrixs are arranged, and promptly the LED of said structure is that matrix is regularly arranged, can strengthen whole luminosity.Advantage simple in structure, long service life that this led light source also has.
Description of drawings
Fig. 1: the structural representation of the utility model embodiment.
The specific embodiment
Be described further below in conjunction with accompanying drawing 1 the utility model.
A kind of led light source as shown in Figure 1 is made of LED8, copper foil circuit plate 7 and aluminium base 1.Aluminium base 1 is provided with the bowl-type groove 3 that several regular matrixs are arranged, and LED8 is installed in the bowl-type groove 3, bowl-type groove 3 the irradiating angle that can strengthen LED8 is set.LED8 is made up of chip 4 and fluorescent material 5, and chip 4 is fixed on bowl-type groove 3 bottom surfaces, and fluorescent material 5 is coated in chip 4 tops.Copper foil circuit plate 7 is arranged on the end face of aluminium base 1, and copper foil circuit plate 7 is connected by gold thread 6 with chip 4, and copper foil circuit plate 7 not only conducts electricity, and can also distribute a part of heat of chip 4 by gold thread 6 conduction.Aluminium base 1 be provided with installing hole 2, the whole LED light source can be installed in the required light fixture easily.
This led light source does not re-use traditional support, and chip 4 is directly arranged in the bowl-type groove 3 on the aluminium base 1, and chip 4 is by aluminium base 1 heat radiation, and chip 4 radiating rates are very fast.
